Halliburton Firm has launched IsoBond, a cement system that reduces sustained casing stress (SCP) at its supply to ship a barrier that minimises fluid loss, shortens transition time, and improves shear bonding
The IsoBond cement system alleviates SCP on all fronts, in contrast to slurries which might be solely designed to mitigate towards fluid loss. With fast gel energy growth and quick slurry transition time, IsoBond lessens annular circulation via cement and will increase the anchoring power to the casing and formation by as much as 40% when in comparison with conventional techniques. This improved shear bonding leads to a cement sheath that’s extra immune to degradation from corrosive fluids. The IsoBond cement system’s transition time to forestall gasoline migration are drastically diminished and the cement’s permeability will be diminished as much as 75% in comparison with different cement techniques.
“By utilising IsoBond to proactively mitigate SCP, our clients minimise threat, cut back price, and restrict their carbon footprint by eliminating the necessity for future remediation,” stated Jim Collins, vice-president of Cementing.
IsoBond is a dry blended cement system that gives vital operational efficiencies for land operations over liquid components, whereas delivering comparable advantages. Utilising the IsoBond cement system achieves a extra environment friendly, sustainable, and economical cement resolution that efficiently manages gasoline migration and annular circulation.
Halliburton has pumped over 15,000 barrels of IsoBond throughout a number of wells in North America and Latin America. The IsoBond cement system will likely be obtainable globally by the top of 2021.
